Abstract

Packet multiplexing has been proposed as a practical method in optical time-division multiplexing. One reasonable approach is to use a packet compression–expansion scheme at the node to match the transmission rate between the ultrafast backbone optical network and slower (electrical) networks. This scheme is superior to the conventional bit interleave scheme in that it does not require an ultrafast switch at the bit rate; instead, switching at the slower header bit rate and/or packet rate is sufficient. In contrast to the bit interleave, we call this scheme compressed optical packet multiplexing (COPM). Here we present an experimental demonstration of an all-optical COPM with use of a 155-Mbit/s video signal that is optically compressed into a 2.64-Gbit/s optical signal and optically expanded back to the original rate with a reasonable bit error rate.
